Configuring llms.txt

Liferay DXP 2026.Q3+ Beta Feature

In Liferay DXP, llms.txt is a plain-text Markdown file served at the root of your domain that gives large language models (LLMs) a curated overview of your site. It lists your most important pages and resources so AI tools can surface authoritative information — rather than relying on general crawling — when summarizing or answering questions about your site.

You can configure llms.txt at the instance level or at the site level. When a request arrives at a site’s virtual hostname, Liferay DXP serves that site’s content and ignores the instance-level configuration; requests to any other host use the instance-level content.

Important

Configuring llms.txt requires the llms.txt beta feature flag. An administrator must enable it before the option appears.

Configuring Instance-Level llms.txt

Instance-level llms.txt is served at the instance’s domain ([domain]/llms.txt) for any request whose host is not a site’s virtual hostname.

1. Open the Global Menu () and navigate to Control Panel → Configuration → Instance Settings.

2. Select SEO under Platform and click llms.txt.

3. Check Enable llms.txt.

4. In the llms.txt Content section, enter Markdown content for the file. A typical llms.txt file starts with an H1 title and a short blockquote summary, followed by sections of links to your most important pages:

   # Acme Corporation
   
   > Acme Corporation builds industrial widgets and supports enterprise customers.
   
   ## Docs
   
   - [Product Overview](https://www.example.com/products): Widget catalog and specifications.
   - [Support](https://www.example.com/support): Guides and troubleshooting.
   
   ## Policies
   
   - [Privacy Policy](https://www.example.com/privacy)
   

5. Click Save.

Your content is now served at [domain]/llms.txt.

Configuring Site-Level llms.txt

Site-level llms.txt applies to a specific site and overrides the instance-level configuration for requests that match the site’s virtual hostname. The llms.txt option appears in Site Settings only when the site has a virtual host configured on its public pages.

1. Open the Site Menu () and go to Configuration → Site Settings.

2. Select SEO and click llms.txt.

3. Check Enable llms.txt.

4. In the llms.txt Content section, enter Markdown content for the file.

5. Click Save.

Your content is now served at [virtual-hostname]/llms.txt.

If llms.txt is disabled — at the site level for a virtual-hostname request, or at the instance level otherwise — the URL returns a 404 (Not Found). A site with llms.txt disabled does not fall back to instance-level content.
